Comparison of PMF and LEAF as Optical Fibre Stress and Temperature Sensing Elements
(2013)We experimentally investigate the sensitivity of PMF and LEAF fibre. The design of a stress sensor gave the best sensitivity of 0.051 kg -1 while that of a temperature sensor, gave the best sensitivity of 0.181 0C1 -
Forward Raman Amplification Characterization in Optical Networks
(2014)Optical networks that apply the technology of dense wavelength-division multiplexing (DWDM) have recently resulted in a considerable increase in existing telecommunications infrastructures. They are expected to play a ... -
An all Optical VCSEL Wavelength Conversion for Optical Fibre Access Networks
(Research Gate, 2016)A cheap, scalable and efficient optical wavelength conversion and optical path switching technique for access networks is experimentally demonstrated. Wavelength conversion is used in wavelength division multiplexed (WDM) ... -
Modeling of ring resonators as optical Filters using MEEP
(2016)Ring Resonators are key component in modern optical networks. Their size allows high density integration in optical photonic circuits due to the use of high index contrast. Ring Resonators based filters in wavelength ... -
Impact of Transformational Leadership Style On Secondary School Students’ Academic Achievement in Mbeere South Sub-County, Embu County, Kenya
(2016)Globally, education is considered as the key drive of any country’s development. This explains the reason why academic achievement is given a lot of importance in the schooling process. In this respect and specifically ... -
Teaching of the integrated topics on drug abuse as a strategy to eradicate drug abuse among secondary school students in Machakos District, Kenya
(2012)The problem of drug abuse has been an area of concern in Kenya for the last two decades. The previous studies carried out in this area revealed that drug abuse has been on the increase at the secondary school level in ... -
The benefits of mainstreaming environmental education in the school curriculum
(Emerging Academy Resources, 2013)The mismanagement and even over- exploitation of environment has been an area of concern globally in the last three decades. This is closely related to human activities such as mining, human settlement and agriculture. ... -
The Need to Integrate Themes of Environmental Education in the School Curriculum in Kenya
(HRmars, 2013)Globally, the environment is under pressure from climatic variability and anthropogenic activities including deforestation, wetland and water catchment destruction, agro-chemicals use and urbanization among others. The ... -
The dilemma of career choice: a case study of Kenyan secondary school students
(Scholarly Research Journal for Interdisciplinary Studies, 2012)The purpose of this study was to investigate the variables that influence career choice among secondary school students in Kenya. The study was guided by two objectives: to determine the influence of peer groups on ... -
Effects of Polarization Mode Dispersion (PMD) on Raman Gain and PMD Measurement using an Optical Fibre Raman Amplifier
(IEEE, 2013-09-09)We experimentally investigate the effects of increase of the differential group delay (DGD) on Raman gain and gain value. It was found that the increase of DGD values lead to the formation and the increase in the number ... -
A 1550 nm All-Optical VCSEL-to-VCSEL Wavelength Conversion of a 8.5 Gb/s Data Signal and Transmission over a 24.7 km Fibre
(International Society for Optics and Photonics, 2017)For the first time, we demonstrate, VCSEL-to-VCSEL wavelength conversion within the low attenuation 1550 nm transmission window, including transmission over fibre and bit error rate (BER) performance characterization. ... -

(2016)This study addresses the effects of selected factors on implementation of inclusive education in regular schools. Objective of the study was to assess the effects of implementation of inclusive education in the programme ... -
Effects of Teacher’s Perception of School Environment On Pupil’s Academic Performance in an Inclusive Classroom: Kenyan Perspective
(2017)Despite education being one of the basic human rights and an empowerment prerequisite, there are various factors that affect the provision of quality education in inclusive public primary schools in Kenya. This paper ... -
Influence of Teacher Characteristics on Academic Performance of Learners with Hearing Impairment in KCPE in Special Primary Schools in Selected Counties, Kenya.
(2019)This study explored the relationships between selected teacher characteristics and academic performance of learners with hearing impairment in Kenya Certificate of Primary Education (KCPE) in special primary schools ... -
Model Post Disaster Reconstruction in Third World Countries, (Case of El Nino Emergency Project– Kenya)
(2007)Following El Nino phenomena that occurred between November 1997 and March 1998, heavy rainfall all over the country caused floods that impacted thirty-five of the seventy-six administrative districts and the provincial ... -
Interactive comment on “A model of landslide triggering by transient pressure waves
(Hydrology and Earth System Sciences, 2014)Hydraulic diffusivity coefficient in Iverson’s (2000) paper and Pressure head diffusivity coefficient in our manuscript may appear as a matter of semantics, but they do not describe the same physical process, as indicated ... -
Indigenous Construction Technologies in Flood-Prone Areas of Western Kenya
(2007)Shelter and sanitation are essential for the well-being and development of most societies. The approach and technology for the provision of shelter and sanitation varies with the social, economic and environmental ... -
BIOSAN Latrine for Refugee Camps
(2010)Provision for energy needs, safe water supply and sustenance of environmental quality are among the topmost challenges facing the present human society. Water and sanitation inadequacies also hinder economic and social ... -
Re-evaluating the relevance and quality of education in Kenya: The Role of Mount Kenya University
(2015)The issue of Quality and relevance of Education is a topical area of concern. However, there is no general consensus on the concept of Quality because, like beauty, Quality is in the eyes of the beholder (i.e, Government, ... -
Relationship Between Learning Strategies And Student Performance In Physics In Public Secondary Schools In Nakuru East Sub-County, Kenya
(Open Access Publishing Group, 2018)Education is a key pillar in the Kenya vision 2030 and is also critical to the attainment of sustainable development goals (SDG’s). Dismal academic achievement by students across all levels of education is therefore ...
